Keres’ PRO EXTEND magazine release features a patent pending design that improves magazine release access and indexing, allowing for faster magazine changes with enhanced ergonomics and comfort.
SIG Sauer produced two different version of their magazine release for the P320. Keres Dynamics is proud to offer our PRO EXTEND magazine release in two generations to be compatible with both SIG Sauer designs. To identify which version you have, look for the following:
- There is a dimple on the side of frame where the access port is located for removing the magazine release.
- With the factory magazine release removed, compare the cutouts at the end opposite of the thumb pad to the diagram shown here.
- This extended magazine release is designed to work with factory Sig P320 frames. It will not fit the X-Series frames.
